"My husband and I are both kind of like, it's going to happen. And trust me, we're at the point where both of our parents are hinting, and they're like, 'Okay, we're ready. You guys have been married a couple of years now,' " she said at the time.

Greene and Khoury tied the knot in July 2018 in San Jose, California.

"The ceremony was beautiful," a source told PEOPLE at the time, adding that the couple came up with a unique way to decide who would read their vows first.

"Paul and Ashley [played] rock-paper-scissors to decide who would say their vows first during the ceremony," the insider said. "Ashley ended up 'losing' and went first."

It was a moment of fun, but the vows themselves were much more serious. "They wrote their own vows," the source explained. "It was very emotional and there were definitely some tears.

To celebrate their nuptials, the couple honeymooned in Hawaii.
